How long does it take for nasopharyngeal carcinoma to become cancer

summary

Two or three years ago, I had a soft knot near my hair on my left neck. Squeezing it would secrete a small amount of white substance like bean curd residue, which had a bad smell. It is said that this may be the manifestation of cancer (such as nasopharyngeal carcinoma). I wonder if it is? How long does nasopharyngeal carcinoma take? Let's listen to experts' opinions.

How long does it take for nasopharyngeal carcinoma to become cancer

First, the causes of nasopharyngeal carcinoma are: the incidence of nasopharyngeal carcinoma is related to heredity and nitrosamines. Apart from the genetic reason, nitrosamine is the main carcinogen in pickled food. So we should eat less pickled food, barbecue food and more fruits and vegetables. This can prevent nasopharyngeal cancer, and a series of digestive tract cancer.

Second, the causes of nasopharyngeal carcinoma are: the incidence of nasopharyngeal carcinoma is closely related to environmental factors. The pollution of living environment and air pollution can induce nasopharyngeal carcinoma. Dust, fumes, chemicals, eating habits, genetic factors and so on in the occupational environment have a certain relationship. We should pay attention to these factors that are easy to cause cancer in our daily life.

Third, the causes of nasopharyngeal carcinoma are: environment and diet can easily lead to nasopharyngeal carcinoma. The content of trace element nickel in rice and water in high incidence area of nasopharyngeal carcinoma is higher than that in low incidence area. In the hair of NPC patients, nickel content is also high. Nickel may be a cancer promoting factor, leading to a high incidence of nasopharyngeal carcinoma. Dinitropropazine is associated with nasopharyngeal carcinoma.

matters needing attention

Radiotherapy is always the first choice for nasopharyngeal carcinoma. The 5-year survival rate is about 45%. Chemotherapy was used after radiotherapy to improve the curative effect and reduce the radiation reaction. If the tumor recurres after radiotherapy or is not sensitive or even ineffective to radiotherapy, surgery can be used. At present, the recovery rate of nasopharyngeal carcinoma is still very high.
